This display is either created through the Displays->Special menu or through the Transects menu in the Transect View.

This display control is a representation of the set of transects that are defined by the transect resource. Not only does it have its own state (that can be saved in a bundle for example) it also writes out any transects you may create or change into your local IDV state directory in a transects.xml file.

In this control there is only one shape that you can draw with, the Transect Line. This control also shows a non-editable Transect Shape which displays the full transect line used by any Transect Views. We call these the "Active Transects". There are also a set of transect lines that are non-editable that are from the system transects property.

For an active transect, if the Transect View that it represents has a max distance set then the transect will show this max distance as a rectangular box.

• Automatically update transects

  When this is selected any changes you do are automatically applied to any Transect Views and are also written out into the transects.xml file.

• Show transects

  This toggles the visibility of the regular transects.

• Show active transects

  This toggles the visibility of the active transects.
